How to troubleshoot a malfunctioning engine in a Vauxhall Movano?

I have recently noticed that my Vauxhall Movano's engine is running rough and it takes a while to start. What could be causing this issue and how can I fix it?

It's likely that your spark plugs or ignition coils need to be replaced. Try checking and replacing those first.

Another possible cause could be a malfunctioning fuel pump. You may need to get it checked and replaced if necessary.

Make sure to also check your air and fuel filters. They could be clogged and causing issues with your engine.

If none of the above solutions work, it might be a problem with the engine control unit. It's best to bring it to a professional mechanic for further inspection.
